Plant Slant
Perhaps you've noticed, in potted plants especially, a collective leaning and growth toward the sun. Upon rotating a flower pot such that the leaves face the opposite direction, the leaves will turn again toward the light source (and reasonably so, as they receive the most energy this way.) In turn, this shifting gives strength to their stems, and serves to add overall fortification to the whole plant, as well as to continue growth into its intended characteristics and function.

The Sun.
Coronal Loops
"Magnetism made visible: That describes virtually every feature on the sun, from sunspots to these soaring structures, called loops. Loops easily reach the height of ten Earths. Energy generated by the dynamics of smaller loops is likely the source of the solar corona's mysterious heat."

"Why is the halo-like corona, visible from Earth only during a total eclipse, hundreds—even thousands—of times hotter than the sun's surface? That's one of the questions that keep scientists looking straight at the sun."
